【摘要】 <正>Superconducting nanowire single-photon detectors (SNSPDs)with low energy gaps exhibit superior single-photon sensitivity at infrared wavelengths [1], and state-of-the-art SNSPDs have the potential to meet the stringent demands of mid-IR (MIR) detection[2]. However, the nanowire thickness (～λ/1000–λ/600) and width(～λ/166–λ/60) are much smaller than those at MIR wavelengths,which results in weak absorption with a low detection efficiency[3].更多还原
